Implementation of a Program for Appendicitis MRI in a Pediatric Hospital.

MRI is increasingly used as an alternate to CT for the evaluation of suspected appendicitis in pediatric patients presenting to the emergency department (ED) with abdominal pain, when further imaging is needed after an initial ultrasound examination. The available literature shows a similar diagnostic performance of MRI and CT in this setting. At the authors' institution, to evaluate for appendicitis in children in the ED, MRI is performed using a rapid three-sequence free-breathing protocol without IV contrast media. Implementation of an MRI program for appendicitis in children involves multiple steps, including determination of imaging resource availability, collaboration with other services to develop imaging pathways, widespread educational efforts, and regular quality review. Such programs can face numerous practice-specific challenges, such as those involving scanner capacity, costs, and buy-in of impacted groups. Nonetheless, through careful consideration of these factors, MRI can be used to positively impact the care of children presenting to the ED with suspected appendicitis. This Clinical Perspective aims to provide guidance on the development of a program for appendicitis MRI in children, drawing on one institution's experience while highlighting the advantages of MRI and practical strategies for overcoming potential barriers.

Rapid, free-breathing non-contrast MRI for first-line imaging evaluation of ovarian torsion in the emergency department.

BACKGROUND: Transabdominal ultrasound (US) is first-line imaging to evaluate ovaries in girls presenting to the emergency department (ED) with suspected ovarian torsion. Ovaries may be difficult to visualize sonographically; therefore, prompt diagnosis using US alone can be challenging. Rapid MRI as first-line imaging may help streamline patient throughput, especially with increasing MRI availability in the ED. OBJECTIVE: To assess feasibility of rapid MRI for diagnosis of ovarian torsion. MATERIALS AND METHODS: A retrospective, single-center IRB approved study of MRI performed in female pediatric patients presenting with abdominopelvic pain from August 2022 to January 2023. Imaging occurred according to one of three clinical pathways (US-first approach vs MRI-first approach vs US + MRI-second-line approach). A rapid three-sequence free-breathing MRI protocol was utilized. Frequency of ovarian torsion and secondary diagnoses was recorded. Length of MR scan time, time from ED arrival to time of diagnosis, and whether patient had US prior to MR exam were obtained. A historical cohort of patients with US only performed for assessment of ovarian torsion were evaluated for length of the US examination and time from ED arrival to time of diagnosis. Intervals were compared using the uncorrected Fisher's least significant difference and Turkey's multiple comparison tests. RESULTS: A total of 140 MRI exams (mean age 14.6 years) and 248 historical US exams (mean age 13.5 years) were included. Of the patients with MRI, 41 (29%) patients were imaged with US + MRI and 99 (71%) imaged with MRI only; 4% (6/140) MR exams were suspicious for ovarian torsion, with one true positive case (1/6 TP) and 5 false positive cases (5/6 FP); 26.4% (37/140) of exams had secondary diagnoses. Median MRI scan time was 11.4 min (4.4) vs median historical US scan time was 24.1 min (19.7) (P<0.001). Median time from arrival in ED to MRI read was 242 (140). Median time from arrival in ED to US only read was 268 min (148). This was not a statistically significant difference when compared to the MRI only cohort. CONCLUSION: First-line MRI imaging for evaluation of ovarian torsion is a rapid and feasible imaging modality for female patients in the emergent setting.

Harms in Encouraging Social Media Use for Individual Academic Advancement.

In academic medicine, the use of social media to share accomplishments is important for various purposes that facilitate academic advancement. However, social media engagement as a criterion for academic advancement is not based on evidence and can cause individual harms related to pressure, expectations, competition, and discomfort.

Practice Patterns in Use of MRI for Appendicitis in the Emergency Department at Children's Hospitals: Results of a National Survey.

This study reports results of a national survey of member institutions of the Society of Chiefs of Radiology at Children's Hospitals regarding use of MRI for appendicitis in the emergency department (ED); respondents from 39 of 100 surveyed institutions participated. A total of 21 of 39 institutions perform MRI for acute appendicitis in the ED; 17 of 21 institutions perform MRI only after an initial ultrasound examination. The number of MRI sequences ranges from three to eight. The estimated room time ranges from 8 to 30 minutes.

Burnout Is the Symptom, Moral Injury Is the Cause: The Need for Systems-Level Changes in Radiology.

Burnout. Wellness. Resiliency. Self-care. These buzzwords have become commonplace and the topics of articles, webinars, and lectures in medicine. Opinions vary about the most effective initiatives to optimize radiologist wellness and mitigate burnout. Despite ongoing efforts, burnout continues to grow. Although individual-directed interventions play a role, the greater leverage lies with practice- and organization-led initiatives.

Gender disparity in academic advancement: exploring differences among adult and pediatric radiologists.

BACKGROUND: Gender imbalance in research output and academic rank in academic radiology is well-documented and long-standing. Less is known regarding this imbalance among pediatric radiologists. OBJECTIVE: To characterize gender differences for academic rank and scholarly productivity of pediatric radiologists relative to adult radiologists. MATERIALS AND METHODS: During summer 2021, faculty data for the top 10 U.S. News & World Report ranked adult radiology programs and the top 12 largest pediatric hospital radiology departments were collected. Information regarding self-reported gender, age, years of practice and academic rank was accessed from institutional websites and public provider databases. The h-index and the number of publications were acquired via Scopus. Group comparisons were performed using Mann-Whitney and chi-square tests. RESULTS: Three hundred and sixty-four (160 women) pediatric and 1,170 (468 women) adult radiologists were included. Compared to adult radiologists, there were significantly fewer pediatric radiologists in advanced ranks (associate or full professor) (P = 0.024), driven by differences between male (P = 0.033) but not female radiologists (P = 0.67). Among pediatric radiologists, there was no significant difference in years in practice (P = 0.29) between males and females. There also was no significant difference in academic rank by gender (P = 0.37), different from adult radiology where men outnumber women in advanced ranks (P < 0.001). Male pediatric radiologists displayed higher academic productivity (h-index: 9.0 vs. 7.0; P = 0.01 and number of publications: 31 vs. 18; P = 0.003) than their female colleagues. CONCLUSION: Academic pediatric radiology seems to have more equitable academic advancement than academic adult radiology. Despite similar time in the workforce, academic output among female pediatric radiologists lags that of their male colleagues.

Impact of coronavirus disease 2019 on pediatric intestinal intussusception in the United States.

BACKGROUND: Masking and social distancing to mitigate the spread of the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) virus curbed the spread of other viruses. Given a potential link between viral illnesses and ileocolic intussusception, the purpose of this study is to characterize trends in incidence, diagnosis and management of pediatric intussusception in the United States in the context of the coronavirus disease 2019 (COVID-19) pandemic. MATERIALS AND METHODS: This cross-sectional retrospective study used the Pediatric Hospital Information System and included children (ages 0-17 years) with a primary diagnosis of intussusception (ICD-10 [International Classification of Diseases, Tenth Revision]: K56.1) from January 2018 to December 2021. Descriptive statistics and chi-square analyses were used to characterize and compare proportions pre-COVID (2018 and 2019) to 2020 and 2021. RESULTS: Eight thousand one hundred forty-three encounters met inclusion criteria. Intussusception diagnoses declined in 2020 (n = 1,480) compared to 2019 (n = 2,321) and 2018 (n = 2,171) but returned to pre-COVID levels in 2021 (n = 2,171). Patient age was similar across years (mean age in years: 2018: 2.3; 2019: 2.1; 2020: 2.3; 2021: 2.3). There was no significant change in the proportion of patients who underwent imaging in 2020 (96% [1,415/1,480]) compared to the other years in the study (2018: 96% [2,093/2,171], P = 0.21; 2019: 97% [2,253/2,321], P = 0.80; 2021: 96% [1,415/1,480], P = 0.85). There was a statistically significant but minimal increase in the proportion of cases treated with surgery in 2020 compared to 2019 (2020: 17.8% vs. 2019: 15%, P = 0.02); however, this was not replicated in the pairwise comparison of 2020 to 2018 (2020: 17.8% vs. 2018: 16.4%, P = 0.23). There was a statistically significant increase in the proportion of cases treated with surgery in 2020 compared to 2021 (2020: 17.8% vs. 2021: 14%, P = 0.001). CONCLUSION: Pediatric intussusception diagnoses decreased at a national level in 2020 compared to previous years, with a rebound increase in 2021. This may reflect a secondary benefit of public health interventions imposed to curb the spread of COVID-19.

Comparison of MRI appendix biometrics in children with and without acute appendicitis.

OBJECTIVES: The goal of this study is to improve MRI-specific diagnostic criteria for pediatric appendicitis through comparison of normal and abnormal appendix-related imaging features. METHODS: A retrospective multireader-multicase design was used, including non-contrast MRI performed for suspected pediatric appendicitis following non-diagnostic US from January 2014 to December 2017. Positive diagnosis was defined by surgical pathology or symptom resolution after antibiotics. Four pediatric radiologists independently graded study biometrics while blinded to clinical data. Balanced complete block design was used to determine performance characteristics. RESULTS: Global diagnosis of appendicitis (208 studies) had sensitivity 90.6% and specificity 97.7%. Median appendix diameter was 10.4 mm among positive cases and 5.8 mm among negative cases (p < 0.001) with an optimal diagnostic cutoff of 7.5 mm (sensitivity 89.4%, specificity 86.5%). Median appendix wall thickness was 2.6 mm among positive cases and 1.7 mm among negative cases (p < 0.001) with an optimal diagnostic cutoff of 2.3 mm (sensitivity 63.1%, specificity 82.9%). Performance characteristics for qualitative appendix features included distinguishable appendix luminal signal (sensitivity 89.6%, specificity 83.7%), intraluminal fluid-signal intensity (sensitivity 63.6%; specificity 52.3%), intraluminal signal intermediate between fluid and bowel wall (sensitivity 91.0%; specificity 37.1%), appendicolith (sensitivity 34.9%; specificity 100.0%), intraluminal layering (sensitivity 25.9%; specificity 100.0%), hyperintense appendix wall signal (sensitivity 31.7%; specificity 100.0%), periappendiceal fluid (sensitivity 66.8%; specificity 72.5%), periappendiceal fatty edema (sensitivity 91.3%; specificity 94.5%), and free pelvic fluid (sensitivity 88.5%; specificity 26.0). CONCLUSIONS: This study provides MRI-specific performance of pediatric appendicitis quantitative and qualitative biometrics with peri-appendiceal fatty edema, appendix diameter > 7.5 mm, and distinguishable appendix luminal signal demonstrating the highest overall accuracy. KEY POINTS: • This retrospective multireader-multicase study characterized magnetic resonance imaging-specific diagnostic accuracy of quantitative and qualitative biometrics for pediatric appendicitis. • The optimal quantitative diagnostic thresholds for an abnormal pediatric appendix at MRI included diameter and wall thickness of 7.5 mm and 2.3 mm, respectively. • Qualitative imaging biometrics with high specificity for pediatric appendicitis on MRI included the presence of distinguishable appendix lumen signal from wall signal, appendicolith, intraluminal fluid-fluid layer, appendix wall hyperintensity, and peri-appendiceal fatty edema.

Gender trends in authorship of Pediatric Radiology publications and impact of the COVID-19 pandemic.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has heightened existing gender differences in academic productivity in medicine. There have been discrepant repercussions for women in academics due to the pandemic, including fewer publications, potentially impacting academic advancement. OBJECTIVE: To evaluate trends over time in the gender of authors of manuscripts submitted to Pediatric Radiology. MATERIALS AND METHODS: This retrospective review of unsolicited manuscripts submitted to Pediatric Radiology from January 2017 to December 2020 included only submissions from North America. For each submission, genders of the first, last (senior) and corresponding authors were inferred by inspection or confirmed by internet search. Chi-square and Fisher exact tests were used to compare authorship gender proportions. Quarterly comparisons between 2019 and 2020 were performed to assess for differences during the COVID-19 pandemic. RESULTS: Between 2017 and 2020, 1,018 manuscripts were submitted. There was no significant difference in female authorship over time (P > 0.05 for first, last and corresponding authors), but there was an increase in female first authorship (38.6% in 2017, 43.2% in 2020). The frequencies of female first (P = 0.03) and last (P = 0.01) authors were significantly higher for educational manuscripts (reviews and pictorial essays) versus other manuscript types. Manuscript submissions increased in the second quarter of 2020; however, there was a statistically significant decrease in last authorship by women during this period (P = 0.02). CONCLUSION: Female authorship of manuscripts submitted to Pediatric Radiology has remained relatively stable between 2017 and 2020. During the early phase (March-May 2020) of the COVID-19 pandemic, female last authorship was significantly lower versus the previous year.

Leveraging diversity, equity and inclusion for promoting wellness in the radiology workplace.

Over the last decade, health care professionals in the field of radiology have experienced increasing rates of burnout. A study in 2017 showed high prevalence of burnout in pediatric radiology, and other studies have identified several drivers for burnout. An important factor in promoting wellness and mitigating burnout is leveraging diversity, equity and inclusion in the workplace. This manuscript highlights the importance of diversity in high-functioning teams as well as the critical role of equity and inclusion in the workplace to help create an organization where people belong and can effectively succeed.

Current State of Imaging of Pediatric Pancreatitis: AJR Expert Panel Narrative Review.

Pancreatitis is as common in children as it is in adults, though causes and accepted imaging strategies differ in children. In this narrative review we discuss the epidemiology of childhood pancreatitis and key imaging features for pediatric acute, acute recurrent, and chronic pancreatitis. We rely heavily on our collective experience in discussing advantages and disadvantages of different imaging modalities; practical tips for optimization of ultrasound, CT, and MRI with MRCP in children; and image interpretation pearls. Challenges and considerations unique to imaging pediatric pancreatitis are discussed, including timing of imaging, role of secretin-enhanced MRCP, utility of urgent MRI, severity prediction, autoimmune pancreatitis, and best methods for serial imaging. We suggest a methodical approach to pancreatic MRI interpretation in children and have included a sample structured report, and we provide consensus statements according to our experience imaging children with pancreatitis.

Pediatric Panoramic Radiography: Techniques, Artifacts, and Interpretation.

Panoramic radiography, particularly in the pediatric population, is rarely addressed in the radiology literature. The authors provide an in-depth discussion of how these images are acquired, what artifacts can be visualized, and how to mitigate these artifacts. Dental anatomy, as well as relevant osseous and soft-tissue anatomy visible on a panoramic image, are reviewed. The appearance of the normal pediatric panoramic radiograph, with an emphasis on the dental follicle, is discussed, as well as how to differentiate this normal structure from underlying pathologic conditions. The most commonly encountered pathologic conditions of carious disease and trauma are emphasized. A systematic approach to diagnosing mass lesions and their appropriate work-up, including multimodality imaging examples of relevant pathologic conditions, is also provided. Finally, congenital anomalies, including some of the more commonly encountered dysplasias, are reviewed. The authors provide a concise review of the relevant information needed to confidently interpret a pediatric panoramic radiograph.

Pancreatic Masses in Children and Young Adults: Multimodality Review with Pathologic Correlation.

Masses and masslike lesions of the pancreas are uncommon in the pediatric population. However, owing to overlapping clinical and imaging features, it can be challenging to differentiate the various causes of pediatric pancreatic masses at initial patient presentation. Clinical data such as patient age, signs and symptoms at presentation, laboratory test results, and potential underlying cancer predisposition syndrome can be helpful when formulating a differential diagnosis. US may be the first imaging study to depict a pancreatic mass in a child, as this examination is frequently performed in children with nonspecific abdominal signs and symptoms because of its wide availability and relatively low cost and the lack of a need for sedation or anesthesia. CT or MRI is typically required for more thorough characterization of the mass and surgical planning. Complete characterization of pancreatic masses includes assessment of vascular involvement, local invasion, and extrapancreatic spread of tumor. The authors provide an up-to-date comprehensive review of the clinical manifestations, histopathologic features, and imaging findings of primary and secondary tumors of the pancreas in children and young adults. Advances in imaging, current prognostic information, and treatment paradigms also are highlighted. Finally, nontumorous masslike lesions of the pediatric pancreas, including vascular malformations, cystic disorders (eg, von Hippel-Lindau syndrome, cystic fibrosis), intrapancreatic accessory spleen, and autoimmune pancreatitis, are discussed. Online supplemental material is available for this article. ©RSNA, 2021.

Evaluation of stress and anxiety caused by the coronavirus disease 2019 (COVID-19) pandemic in pediatric radiology.

BACKGROUND: Work-related stress and burnout were documented to be high among pediatric radiologists prior to the coronavirus disease 2019 (COVID-19) pandemic. New challenges arose from the COVID-19 pandemic, potentially introducing new stressors and anxieties. OBJECTIVE: To evaluate potential sources of stress and anxiety for pediatric radiology faculty during the early phase of the COVID-19 pandemic. MATERIALS AND METHODS: We conducted a survey of attending physician members of the Society for Pediatric Radiology in North America from April 27, 2020, to May 22, 2020. The response rate was 21% (251/1,206). Survey questions included demographic information and questions regarding working remotely, personal protective equipment, redeployment, personal wellness, wellness resources and financial concerns. A psychometrician reviewed the questions to ensure minimal risk of misinterpretation. RESULTS: Median age of respondents was 48 years (range 33-70 years) with median number of years in practice of 14 (range 1-45 years). Fifty-three percent of respondents were women and 46% were men. Because of an increase in remote work, 69% of respondents endorsed feeling more isolated from a lack of regular interaction with colleagues. Fifty-three percent of respondents indicated that it is challenging to work remotely while overseeing home schooling for children. In comparison to men, women reported overall higher work-related stress and anxiety (P=0.02), higher feelings of guilt from radiology staff (i.e. technologists and nurses) being more exposed to COVID-19 (P=0.02) and higher levels of stress providing for dependents (P=0.04). Most respondents thought that departmental leadership was effective and respondents were not concerned about meeting financial obligations or job loss. CONCLUSION: The early phase of the COVID-19 pandemic caused additional stress and anxiety for pediatric radiology faculty and disproportionally affected women. Given the continuously evolving state of the COVID-19 pandemic, these results could aid in planning and implementation of future strategies to combat burnout in radiology. Specific attention should be directed to different stressors experienced by female versus male radiologists, especially in regard to dependent care.

The growing issue of burnout in radiology - a survey-based evaluation of driving factors and potential impacts in pediatric radiologists.

BACKGROUND: Burnout in medicine, and specifically radiology, has been receiving more attention. Little data-driven literature is available regarding risk factors/causes to ultimately help guide the development of potential solutions. OBJECTIVE: To survey pediatric radiologists, a cohort with a documented high prevalence of burnout, and to understand the impact of clinical demands on nonclinical tasks and the implications of burnout on mental health. MATERIALS AND METHODS: A survey of Society for Pediatric Radiology (SPR) North America attendings was performed regarding institutional factors contributing to burnout, including call burden, clinical demands, departmental support and administrative/academic tasks. Questions regarding mental health and wellness resources were also included. Generalized linear modeling assuming binomial distribution was used for analyses with SAS 9.4. RESULTS: The response rate was 305/1,282 (24%) with 53% of respondents female. Respondents reported that both the number and complexity of clinical cases have increased since they first started practice as an attending, while the time for interpretation has not changed, P<0.0001. Using a scale of 0 (never), 1 (rarely), 2 (sometimes), 3 (frequently) and 4 (always), covering multiple hospitals (2.2) and administrative tasks (2.4) were the most stressful job factors. For those in administrative roles, the most stressful job factors were job-related tasks affected teaching duties (2.0) and decreased overall job satisfaction (2.0). Of the respondents, 52% said they know a physician affected by work stress-related mental illness and 25% know a physician who has contemplated or committed suicide. While 39% of the respondents have resources available to address burnout, only 33% utilize these resources. CONCLUSION: Increasing clinical demands and additional institutional/departmental factors play a potential role in burnout, which has serious implications for the mental health of pediatric radiologists.

Intravenous gadolinium-based hepatocyte-specific contrast agents (HSCAs) for contrast-enhanced liver magnetic resonance imaging in pediatric patients: what the radiologist should know.

Hepatocyte-specific contrast agents (HSCAs) are a group of intravenous gadolinium-based MRI contrast agents that can be used to characterize hepatobiliary pathology. The mechanism by which these agents are taken up by hepatocytes and partially excreted into the biliary tree improves characterization of hepatic lesions and biliary abnormalities relative to conventional extracellular gadolinium-based contrast agents (GBCAs). This manuscript presents an overview of HSCA use in pediatric patients with the intent to provide radiologists a guide for clinical use. We review available HSCAs and discuss dosing and age specifications for use in children. We also review various hepatic and biliary indications for HSCA use in children, with emphasis on the imaging characteristics distinct to HSCAs, as well as discussion of pitfalls one can encounter when imaging with HSCAs. Given the growing concern regarding gadolinium deposition in soft tissues and brain, we also discuss safety of HSCA use in children.

Stressors contributing to burnout amongst pediatric radiologists: results from a survey of the Society for Pediatric Radiology.

BACKGROUND: A recent study showed a high prevalence of burnout in pediatric radiology. OBJECTIVE: The purpose of this study is to evaluate potential stressors contributing to burnout in pediatric radiology. MATERIALS AND METHODS: Society for Pediatric Radiology members received an invitation for an anonymous survey evaluating stressors contributing to burnout. Stressors evaluated included call burden, financial stress, work-life balance, health care evolution and job market changes, and radiology as a career choice. Additional questions regarding demographics were obtained. RESULTS: The response rate was 460/1,453 (32%). The prevalence of emotional exhaustion was 66% (286/435), depersonalization was 61% (265/433) and perceived lack of personal accomplishment was 15% (67/436). In a backward selective logistic regression model, work-life imbalance and call burden were the only significant factors predicting higher emotional exhaustion (P<0.001). Using a similar model, work-life imbalance, call burden and decreased rate of reimbursement were significantly associated with higher probability of depersonalization (P=0.033, 0.0002 and 0.015, respectively). Emotional exhaustion and depersonalization were significantly associated with higher odds of a radiologist's wish to work in another medical specialty (P=0.011 and 0.002, respectively). CONCLUSION: Key stressors contributing to burnout in pediatric radiology include work-life imbalance, pediatric call burden and a decreased rate of reimbursement. Burnout in pediatric radiology is a serious issue that needs to be addressed and prioritized on the individual and departmental/institutional levels and further investigated to develop effective interventions to mitigate it.
